IMPROVEMENT IN SHEET-METAL CANS.

The Schedule referred to in the-se Letters Patent and making part of the same.

To all whom'fit may concern:

lie it known that I, FRANZ ALBAUM, of Green Point 'in the-county of Kings and State of N ew York, have invented a new and useful Improvement in Sheet-metal Cans; and I doI hereby declare that the .following is a full, clear, and exact `description thereof,

which will enable others skilled in the art to make and use the saine, reference being had to the accom-4 panying drawing forming part ot' this specification.

The drawingrepresents a side view, partly in section, of' my improved sheet-metal can.

This invention relates to a new manner of' securing the tops and bottoms in sheet-metal cans, with the object of supporting the same firmly, and permitting their rapid application.

My invention consists in forming .the joint, by providing a shoulder ou the can-body for the top to rest on, and in then bending the end'portion ot' the` body over the projecting flange of the top. In this manner the top is held down by the overlapping portion oi' the body, and is also supported by the afore? By the substantial fastening the process ot soldering is greatly simplified, as less attention need be bestowed upon the position of the top and bottom plates.

A, in the drawing,1 epresents thesbody of a sheetmetal can.

B is the top of the same. C

The top has its edges turned up to form a projecting ange, a.

'.Llle bodyi's struck outwardly to form a small shoulder, b, on which the cover rests, and above the said shoulder the upper partof the body is carried over and around' the flanged., as is clearly shown in the drawing.

The cover is .thus supported by the shoulder and held down upon tbe same bythe inward bent portion c of' the can-body. The bottom is or may be secured in the same manner.

- Having thus described my invention,

I claim as new and desire tol secure by Letters Patentl The cam-joint, consisting of the shoulder b, and inward bent end portion c, ou the body, and of the flange a ou the end plate b, substantially as herein shown and described.

The above specification of my invention .signed by me this 28th dav of June, 1870.
